and it consists in the novel features herein after described and claimed. I

An object of the invention is to provide a motor of simple and durable structure especially adapted to be used for operating mechanical toys as for instance merrygorounds, roundabouts, F erris wheels and the like and with the above ob ect in new the motor comprises a frame having a shaft journaled thereon with means for holding the shaft against rotation in one direction only. A worm wheel of especial design is journaled upon the shaft and one end of a coil spring is attached to the worm wheel and the other end of the said spring is attached to the shaft. Another shaft is journaled upon the frame and a worm of especial design is mounted upon the last mentioned shaft and meshes with the said worm wheel. V

In the accompanying drawing :-F1gure- 1 is a side elevation of a toy in the form of a merrygoround with the motor applied.

Fig. 2 is a sectional View of the motor. Fig. 3 is a similar view taken on the line 33 of Fig. 2. Fig. 4- is a similar view taken on the line 4-4: of Fig. 2.

The motor comprises a frame 1 which may be of any suitable or conventional form. A shaft 2 is journaled in the frame 1 and is provided at an end which projects beyond the side of the frame with a handle 3. A

ratchet wheel 4: is fixed to the shaft 2 and a spring pawl .5 is mounted upon the frame 1 and is engagcable with the teeth of the wheel 4: whereby the said wheel and shaft 2 are held against rotation in any but one direction. A worm wheel 6 is looselymounted upon the shaft 2 and is of especial construction anddesign as hereinafter described. A coil spring 7 surrounds the intermediate portion of the shaft 5 and is connected at one end with the ratchet wheel 4 and at its other end with the worm wheel 6. A shaft 8 is journaled upon the frame 1 and is disposed at a right angle to the shaft 2. The shaft 8 is provided in the vicinity of its winding operation of the spring.

lower end with aworm 9 which as shown.

best in detail in Fig. 3 comprises a section of wire spirally wound about the shaft ,8 and having its'convolutions' spaced any suitable means as for instance" solder or the likebeing employed for fixing the worm 9 with relation to the shaft. The teeth of the wheel 6 mesh with the intermediate"convolutions of the'worm 9. v V

The wheel 6 is struck preferably from a 1 piece of sheet metal and is provided with peripheral teeth 10 having at one edge lips 11 disposed at obtuse angles with relation to the plane of the wheel 6 and the teeth 10. These lips 11 are formed from the material which is out from the body portion of the wheel 6 between the adjacent teeth 10 and consequently in the formation of the wheel with the outstanding lips there is no waste of material. The shaft 8 inay be connected with any movable part of a mechanical toy for operating, the toy and as hereinbefore stated the shaft 8 as shown in Fig. l is connected with a merrv-go-round or roundabout.

The operation of the motor is as follows: An operator grasps the handle 3 of the shaft 2 and rotates the shaft whereby the spring 7 is wound upon the shaft and inasmuch as the pawl 5 engages the teeth of the wheel 4 the said wheel and the shaft 2 are restrained against rotation in one direction but may rotate in the other direction during the After the spring has been sufliciently wound as above indicated the shaft 2 remains at rest as does also the wheel 4 but inasmuch as the opposite end of the spring 7 from that end which is connected with the wheel 4; is connected with the wheel 6 and in view of the fact that the wheel 6 is loosely mounted upon the shaft 2 the wheel 6 is rotated under the impulse of the spring 7 and the teeth 10 are carried around the aXis of the shaft 2 and the outstanding lips 11 slide along the intermediate convolutions of the worm 9 and the said worm and shaft 8 are rotated. This action continues until the spring 7 is unwound when it may be rewound andthe same action repeated. Therefore it will be seen that a motor especially adapted to be used for operating toys is provided and that said motor is of simple and durable structure and efficient in its action.

Having described the invention what is claimed is naled for rotation upon the frame and hav- I ing peripheral teeth provided at an edge with outstanding lips disposed at an obtuse angle to the plane of the wheel the said teeth and lips adapted 'to engage the convolutions of the worm.

2. A motor comprising a frame, a shaft journaled thereon,-a rod spirally wound upon the shaft and seeuredthe'reto and constituting a Worm, a spring actuated wheel journaled upon the frame and having peripheral teeth proyided at an edge with lips adapted to encounter the convolutions of the Worm.

8. A motor comprising a frame, a shaft journaled thereon, a worm carried by the shaft, another shaft journaled upon the frame, a ratchet Wheel attached to the last mentioned shaft, a spring pawl mounted upon the frame and engageable with the ratchet Wheel, a worm Wheel loosely mounted upon the last mentioned shaft, a spring wound about the last mentioned shaft and connected at one end with the ratchet wheel "and "at its other end with the worm wheel,

, the said Worm Wheel having peripheral teeth Copies of this patent may be obtained for in cents each, by addressing the Commissioner of Patents,
